Polyatomic Ions- are molecules made up of 2 or more atoms that are considered an ionic group, that is, a molecule with a charge. These form compounds that will contain both ionic and covalent bonds. Table of Polyatomic Ions Rules- Compounds have a first and a last name. 1. Name the cation (+ ion) first (watch for NH4+…ammonium) 2. Name the anion (- ion) second …that is it (no prefixes…except dichromate) (hydrogen carbonate is also called bicarbonate) (hydrogen sulfate is also called bisulfate) Highlight to reveal the names of the formulas Formula | Name | AlPO4 | aluminum phosphate | KNO2 | potassium nitrite | NaHCO3 | sodium hydrogen carbonate | CaCO3 | calcium carbonate | Mg(OH)2 | magnesium hydroxide | Na2CrO4 | sodium chromate | Ba(CN)2 | barium cyanide | K2SO4 | potassium sulfate | NaH2PO4 | sodium dihydrogen phosphate | NH4NO3 | ammonium nitrate | Sn(NO3)2 | tin(II) nitrate | FePO4 | iron(III) phosphate | Cu2SO4 | copper(I) sulfate | Ni(C2H3O2)2 | nickel(II) acetate | HgCO3 | mercury(II) carbonate | Pb(OH)4 | lead(IV) hydroxide | Cu2Cr2O7 | copper(I) dichromate | Cu(ClO3)2 | copper(II) chlorate | FeSO4 | iron(II) sulfate | Hg2(ClO4)2 | mercury(I) perchlorate | KClO3 | potassium chlorate | SnSO4 | tin(II) sulfate | Al(MnO4)3 | aluminum permanganate | Pb(NO3)2 | lead(II) nitrate | Mg3(PO4)2 | magnesium phosphate | CuH2PO4 | copper(I) dihydrogen phosphate | CaHPO4 | calcium hydrogen phosphate | Fe(HCO3)3 | iron(III) hydrogen carbonate | Na2CO3 | sodium carbonate | MnSO4 | manganese(II) sulfate | Ca(ClO3)2 | calcium chlorate | Fe(OH)3 | iron (III) hydroxide | Cu2SO4 | copper(I) sulfate | KMnO4 | potassium permanganate | NaOH | sodium hydroxide | Fe(NO3)2 | iron (II) nitrate |
